VALVE.

T all whom it may concern Be it-known that I, WILLIAM J. SHARKEY, acitizen of United States of America, residing at Pine Bluff, in thecounty of Jefferson and State of'Arkansas, have'inv'ented new and usefulImprovements in Valves, of

which the following is a specification.

This invention relates to locomotive throttle valves, and aims toprovide a construction which is easy of manipulation,

and one which need not be removed from the stand pipe to permitinspection of the boiler.

Valves for the above mentioned purpos with which I am familiar, includean elbow which must be removedfrom' the steam dome to permit inspectionof the boiler,

and this obviously requires considerabletimeand labor. My purpose, is toconstruct a valve to eliminate this trouble.

An important, object of the invention, resides in the simplicity of theconstruction of the valve, thusfutilizing less material,

and occupying less room=when in position for use, than throttle valvesin present day use. J J

v The nature and advantages of the'inven .tion will be better understoodwhen the following detail description is read in connection with theaccompany ng drawings, the lnvention' residing in the 'constructlon,

" combination and arrangement of parts as claimed.

In the drawings forming-part of this application, like numerals ofreference indicate similar parts in the several views, and whereinFigure 1 is a view in elevation of the valve constructed in accordancewith my invention, showing the valve associated with the stand pipe of alocomotive.

Fig. 2 is a vertical sectional view taken 0 line 2-2 of Fig. 3.

base having an enlarged central opening 11 =1 about the ed e of whichrises a short annular flange 12. ii. plurality of standards 13 projectupwardly and inwardly from the wall of the opening 11 of the base, andsupport of smaller diameter than the base 10, and spaced therefrom thedesired distance. Arranged upon the plate" 14 {are crossed guideelements 15 for the valve B, these elements being secured tothe top inany suitable manner and in the form of strips arranged '60 on theirupper ends, a top plate 14.which is edgewise, and of a lengthsubstantially equal to the diameterof the upper side of topplate 14.Both the flange 12 I and the top plate 14, are beveled as at 16, thus'providber of a size to fit nicely overthe cage A,

the valve having inwardly directed upper andlowerflanges 1 8. The'innerperiphery of each flange is provided with a straight portion or-edge 19,anda-beveledportion 20 so that the valve17 readily accommodates edge orportions 19* cooperate with the standards 13 andwith the guidingelements l5'to 'm'aintaina proper position with respect to the valveseat when thevalve is itself to the valve vseats16. The straight movedto an open position. The valve 17 is also provided with an annulargroove 21 arranged intermediate its ends, to accommodate the valveoperating means of well known construction.

In practice, the valve 17 is raised and lowered to an opened and closedposition in the usual well known manner, and when the valve is in anopened position as shown in Fig. 4, the steam enters thepipe atboth thetop and bottom of the valve, as indicated by the arrows in Fig. 4. Whenthe valve'is elevated to an open position, the. straight edges 19 at thebottom of the valve contact the adjacentedges of the standards 18, whilethe straight edges ofthe upper end of the valve contact the adjacentedges of the guiding elements 15, and in this mannerthe valve ismaintained in proper position with regard to the valve seats 16 so as toproperly and effectively engage the seats when the valve is lowered. Theconstruction obviously eliminates the elbow hereinabove referred to inconnection with other valves of this type and could be readilysubstituted for this type of valve without any change in theconstruction of the pipe with whlch it i is associated. The simplicityof the construction is such that it occupies but a small amount ofspace, and also provides for inspection of the boiler without removingthe valve from the pipe. I desire to have it nnderstood that the valvecan be varied in size and configuration without departing from thespirit of the invention.

While it is believedthat from the foregoing description,the nature andadvantages of the invention will be readily apparent, I desire to haveit understood that I do not limit myself to the details herein shownanddescribed and that such changes eled portions to normally engage saidseats,

and: said valve having an annular groove intermediateits ends for, the:purpose specifled. I
